I am a computational biophysicist who studies membranes, lipids, nucleic acids, proteins and dynamics to examine problems from basic physics to drug design. I often collaborate with students on research projects.
I help out with the men’s and women’s Ultimate Frisbee teams every spare moment that I get! I also enjoy cooking, spending time with my wife and three young children. I also enjoy power lifting, although perhaps that’s not fair, as it provides some good examples for my physics classes.
Somewhere in the middle of my undergraduate career, I decided that I wanted to become a professor at a small, liberal arts college. I’ve tried several different careers (from volunteering in inner-city public schools in Chicago with City Year, to working as a computer programmer in the Bay Area during the dot-com boom), but my passion for both teaching and research kept bringing me back to academia. Earlham is the rare place that cares about all community members as people with both academic and non-academic lives, that brings the liberal arts to life in a modern setting, that values teaching excellence alongside research, and that holds Quaker ideals dear. In my experience, our students are all here because they are passionate about something. Even my introductory classes are entirely full of students who genuinely want to learn and explore, and I rarely run into a student who is just taking a class to check off a requirement. Earlham is a small, relatively intimate community, and I’ve found that literally every single student I’ve gotten to know has been an interesting, good person.

I am a computational biophysicist (translation: I like to think like a physicist, think about problems motivated by biology and use simulations as a “computational microscope” with which to examine the world). I study membranes, lipids, nucleic acids, proteins and dynamics to examine problems from basic physics to drug design.

Collaborative student research experiences
While most of the DNA structures that you see in textbooks are right-handed helices called B-DNA, it turns out that DNA can also be found in a left-handed helix, called Z-DNA. This left-handed form is important for relieving torsional strain, and is likely also involved in diverse parts of biochemistry ranging from gene regulation to Alzheimer’s disease. Surprisingly, the biochemical process by which B-DNA is transformed into Z-DNA is still not well understood. Due to the size of the systems involved, direct experimental measurements range from hard to impossible. Our group works with physics, chemistry, computer science and biochemistry students to use computational models to understand this transition.
